Would the ion drive in Deep Space 1 work if the xenon atoms were not changed into ions by the loss of an electron? Explain your answer.

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
